Added explicit language to conf. In R, use

umlautOk = nlevels(na.omit(as.factor(iconv(c("Pre","Prä")))))==2

to test if the settings are honoured. Without this entry, processing of special characters (ä,ü) by Pandoc can lead hang or "index error"

Added post-stop sleep to delay respawning of upstart. On some computers, too fast respawing fails, and shiny server is not started.
